The Printed Materials series is composed of reports and publications about the U.S. military and government. The first set of reports were primarily produced by military groups, notably sections of the Army, Military Intelligence, and General Headquarters Southwest Pacific, on the progress of World War II in the Pacific and European theaters. Many of the reports were initially classified or intended for internal use only and include maps and narrative reports which describe combat operations, including the planning stages, troop movements, events during combat, and the final results. The second set of documents includes government publications and publications by independent scholars and institutes that cover a wider range of topics, including the organization of the executive branch of government (the "Hoover Commission"), the U.S. economy and taxes, and U.S. Department of Commerce reports on business, as well as summaries of the achievements of the branches of the military during World War II and reports on the organization, history, and current problems of the Navy. The unnumbered publications, which are not part of either set, are typically reports to the government by various committees and officials on subjects including discussions of occupied Germany, plans to promote the economic recovery of Europe, and reports of the Supreme Allied Commander on the Mediterranean campaign, as well as the analysis of marine navigation and weather patterns, the contributions of small unit actions, and the health of coal miners.
